Their products aren’t cheap, the low end ones run about $100,000 with the end end models cost in the $250,000 range.

Most of their Jet Packs are actually Rocket packs and only can carry about a minute of fuel. So flight ranges are limited. The Martin JetPack actually uses ducted fans, and claims a 30 minute (at 60 mph) range. it is a bit big and still in the “barely off the ground” phase from what I can tell.
